Hi!
I'm working with nRF51DK with s110 soft device on it. I'm trying to write simple custom service which reads some data from sensors and send it over BLE to Android app...
Hello,
I know the current limit of 15mA to share among all gpio pins.
If I source/sink current in very short bursts (100ns every 1ms) can I draw larger currents than 15...
Dear All,
We are working on a custom board with NRF51822.Everything works fine apart from the timer. What we are doing is that once the board is booted, it reads some values...
Situation:
We are building BLE device that have GATT service showing a analog sensor value.
AIN2 is connected to the sensor. AIN4 is connected to battery.
We would like...
